Hi René


Hi Andrew,

SGMII and fixed-link is rather odd. Why do you need this combination?

BananaPi R64 has a RTL8367S 5+2-port switch, switch interfaces with  
the SOC by a
(H)SGMII and/or RGMII interface. SGMII is mainly used for the LAN ports and
RGMII for the WAN port.

I mimic the SDK software which puts SGMII interface in 2.5GBit  
fixed-link mode.
The RTL8367S switch code also put switch mac in forge 2.5GBit mode.

So this is the reason why I put a fixed-link mode here.

Greats,

René
